Summary

This is my 3rd version of printable LM8UU bushings.

Prusa suggested to me that putting some spring/give in them could be a good idea, so I gave it a go.

They're more than strong enough to handle the forces they get subjected to, and as an added bonus they're far less likely to crack your X-ends when you insert them since they'll happily compress a little.

I replaced a set of my original bushings with these, they're still wearing in but seem to work great so far. It certainly solved the chatter problem I had!

PLEASE NOTE: ABS is not a suitable material for bushings. It's too soft so it has lots of friction and wears quickly. These printed in ABS would be a novelty only, not a useful part.

Testing on an Anet A8 using PLA with 100% infill and a few dabs of white lithium grease. I had to heat up the shaft of a large philips head screw driver, taking a cigar lighter on the shaft to get the LM8UU bushing v3 to turn and expand a little more for smoother movement. I have some real drylin igus rj4jp-01-08 bearings for comparison. The movement on the real igus rj4jp-01-08 bearings can spin on the rod and slide back and forth with ease, one small finger flick and they should move to the other side. Once I got them heated a little to move better they seem pretty good. I will update in a few weeks after further testing .If I don not make an update ....they're probably working :)
